A).
you have your slope domain 4x
and your Y= -10
Answer:
74 mph
Step-by-step explanation:
The driver started driving at s mph.
After 3 hours, the speed became s + 10 mph.
The total time is 11 hours, so 3 hours were driven at s mph and 8 hours were driven at s + 10 mph.
speed = distance/time
distance = speed * time
distance = (distance driven at speed s) + (distance driven at speed s + 10)
894 = s * 3 + (s + 10) * 8
3s + 8s + 80 = 894
11s + 80 = 894
11s = 814
s = 74
Answer: 74 mph
In the last equation it hast to be on the bottom 43 not just 4
X=-2
Y=3
I guessed and checked, works for me most of the time
ok... 14 students and the teacher wants each student to have the same number of slices. There is 8 slices per pizza.
do your factors of 8 and at the same time do your factors of 14
14*4=56
8*7=56
so in order for each student to get the same number of slices he will have to buy 7 pizza and they will get 4 slices each.
